In a repository with mainto/1.0 (to keep maintaining the 1.0.X
series) and fixo/1.0 (to keep fixes that apply to both 1.0.X
series and upwards) branches, "git-name-rev mainto/1.0" answered
just "1.0" making things ambiguous. Show refnames unambiguously
like show-branch does.

Noticed by linux@horizon.com. The first merge parent (typically
"our branch") is ^1, not ^0, and the first other branch is ^2.

It dropped the last hexdigit in the object name.
[jc: Noticed and patch supplied by ALASCM, reworked to apply at
the right place by me]

Make some functions static and convert func() function prototypes to to
func(void). Fix declaration after statement, missing declaration and
redundant declaration warnings.

One caller of deref_tag() was not careful enough to make sure
what deref_tag() returned was not NULL (i.e. we found a tag
object that points at an object we do not have). Fix it, and
warn about refs that point at such an incomplete tag where
needed.

git-name-rev tries to find nice symbolic names for commits. It does so by
walking the commits from the refs. When the symbolic name is ambiguous, the
following heuristic is applied: Try to avoid too many ~'s, and if two ambiguous
names have the same count of ~'s, take the one whose last number is smaller.
With "--tags", the names are derived only from tags.
With "--stdin", the stdin is parsed, and after every sha1 for which a name
could be found, the name is appended. (Try "git log | git name-rev --stdin".)
